FIGURE 7. Gnathopods I–II in Toward a unified taxonomy of Niphargus (Crustacea: Amphipoda): a review of morphological variability

FIGURE 7. Gnathopods I–II. The following parameters were measured: depth and width of coxa II (cxw, cxd), width and length of basis (bl, bw), cl (carpus lenght), propodus length, width, diagonal (pl, pw, pd), basal and distal part of the dactylus (d1,2) (A, B, E: N. dalmatinus, male gnathopod I, C: N. dalmatinus, male gnathopod II, D: N. dalmatinus, female gnathopod II, note the sexually dimorphic shape of the coxa II). Note variable number of palmar (F–I, II: N. grandii [after Sket 1972]) and supporting spines (G: N. kenki [after S. Karaman 1952]) as well as shifted position of denticulated spines (H–I,II: N. salonitanus [after G. Karaman 1984a]). Setae below palmar spine are indicated with ps.
